oval trademark, rather than Hillerich & Bradsby - Louisville
Slugger. The H&B brand denotes a lower grade and lower priced
retail bat. These bats were produced since 1932.The labels pictured below are
dated to the first catalog appearance and could over lap the
new label during the transition year .labels pictured below are

NOTES:

What Does the 125 stand
for? - The number that appears in the center brand is
the catalog number, used to order bats. The "125" is the
catalog number designated for Professional and high quality
store model bats. The highest grade of wood is reserved for all
125 baseball bats. Before the 125 the No. 40 was the highest
quality line of baseball bats in the Louisville Slugger
catalog. The 125 is not the model number. Louisville slugger
began using model numbers on the knob in 1943 then moving the
model number to the barrel in 1977.

The "Powerized" process was
patented by the Hillerich & Bradsby
Co. in 1931 and has pat. pending
beneath the stamp. They introduced
the "Powerized and Bone Rubbed"
logo for the 1932 season and in
1933 and 1934 you will see it
stamped "Powerized and Oil
Tempered" which usually is a very
light heat foil type print.
Beginning in 1935 until present,
they go with just "Powerized" The
Powerized" process is to harden the
surface of the bat much like the
bone rubbed finish of the 1920's. A
1938 Louisville Slugger ad states:
"'Powerizing' is a treatment by a
special patented process that
reduces chipping and peeling to a
minimum, increasing the driving of
the bat and prolongs it's life"

Hand Boned Rubbed
Trade-Mark Stamp.
Bone-Rubbed is common to
bats made in the 1920's

The
"Powerized and Bone Rubbed"
logo stamping is unique to the
1932 season.

1933 & 1934 "Powerized and
Oil Tempered" is
stamped, usually as a very light heat foil
type print.

In 1935 until the present,
they go with just "Powerized"

In 1973 the Registered
Trademark
is added over the "d" in Powerized

Oil Tempered a process used
since the beginning
appeared on the barrel
before migrating to the
oval

Flame Tempered a process
of drying and hardening the
